Modeled hydrodynamic equations for two component plasmas
This work examines the exact hydrodynamic equations describing fluctuations in two component plasmas. Following the Zwanzig-Mori projection operator formalism, four exact hydrodynamic equations are obtained by choosing microscopic density and microscopic current density as dynamical variables for both electrons and ions. The memory functions appearing in these equations are identified as the generalized k and w dependent transport coefficients according to the two fluid and one fluid descriptions of two component plasmas. The time relaxations of the memory functions are modeled so that in the limits k ..-->.. 0 and w ..-->.. 0 the exact hydrodynamic equations reduce to the conventional hydrodynamic equations, and in the limit k ..-->.. 0 and any finite w the ideal gas spectra are produced for electrons and ions. The difference in modeling the memory functions according to the two fluid description and the one fluid description is investiated in detail.
